From a9eddc952870d29aa9df96ab862327eb6afa23d9 Mon Sep 17 00:00:00 2001 From: Zachary Amsden Date: Mon, 5 Mar 2007 00:30:41 -0800 Subject: [PATCH] vmi: fix nohz compile More goo from hrtimers integration. We do compile and run properly with NO_HZ enabled. There was a period when we didn't because of a missing export, but that was since fixed. And with the clocksource code now firmly in place, we can get rid of code that fixes up the wallclock, since this is done in the common infrastructure. This actually fixes a timer bug as well, that was caused by do_settimeofday no longer being callable with interrupts disabled due to the use of on_each_cpu().
